This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B05-MBL20X25S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The MBL replacement upgrades to a riveted rolling-packed body and the current CMSG / DMSG / EMSG sensor switches (the MAL used CS1-M / DS1-M).
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X25S
The AirTAC B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X25S is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 25mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B05-MBL20X25S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X25S
The AirTAC B05-MAL20X25S is a discontinued compact double-acting aluminum mini round cylinder. The leading "B05-" prefix marks this as a robot and manipulator (pick-and-place) dedicated variant, though mechanically it is identical to the base MAL20X25S. Delivering 157 N push and 132 N pull at 0.5 MPa, it is built for light, high-speed automation handling. AirTAC replaced this legacy series with the MBL20X25S, an direct replacement retaining the same 20 mm bore, 25 mm stroke, G1/8 port, and mounting footprint.
This cylinder features a fixed rubber bumper and a self-lubricating front-cover bearing guide that supports the 8 mm carbon-steel rod. The legacy MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Because this SKU includes the -S magnet, it supports position detection via older CS1-M or DS1-M switches; upgrading to the MBL means transitioning to the current CMSG, DMSG, or EMSG sensor family.

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X25S Is Used
Pick-and-Place Manipulators
Ideal for robot arms executing fast 25 mm strokes to transfer small electronic components, utilizing the 157 N push force for secure grip actuation.
PCB Board Handling
Provides precise 25 mm linear movement in tight assembly cells for pushing printed circuit boards into testing fixtures without overwhelming delicate parts.
Light Packaging Diverters
Drives small pneumatic fingers to sort lightweight plastic vials on conveyor lines, where the compact 20 mm aluminum body fits into restricted machinery gaps.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X25S with B05-MBL20X25S
To replace the B05-MAL20X25S, order the MBL20X25S. Confirm your 20 mm bore, 25 mm stroke, G1/8 port, and default PT tapered thread. The -S magnet requires a sensor family change from the legacy CS1-M / DS1-M to the modern CMSG / DMSG / EMSG switches. If your pick-and-place payload needs less force, step down to the 16 mm bore class; if you need more power, step up to the 25 mm bore, which provides 245 N push at 0.5 MPa.
The fixed rubber bumper softens end-of-stroke impacts but is not an adjustable cushion. If your manipulator requires end-of-stroke deceleration control, specify the MBLC variant on the current line. Furthermore, a plain cylinder does not hold its position when air pressure drops. To prevent a dropped payload during an air loss event, install an external rod lock or a pilot-operated check valve.
Upgrade checklist
- ✓ Order the B05-MBL20X25S (same bore/stroke/force)
- ✓ Same G1/8 port and mounting accessories
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Need a cushion? use MBLC (adjustable air cushion)
- ✓ Confirm back cover (CA / U) and thread (PT/NPT/G)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Front/rear covers are threaded — not intended for field disassembly.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U / CM).
- check For new builds, specify the B05-MBL20X25S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X25S FAQ
Yes, the B05-MAL20X25S is discontinued. The direct replacement is the MBL20X25S. The "B05-" prefix simply designated it as a manipulator and pick-and-place dedicated variant of the base MAL20X25S. The MBL20X25S matches the original 20 mm bore, 25 mm stroke, 157 N force, G1/8 port, and mounting dimensions, but uses a riveted body instead of threaded covers.
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, the push force is 220 N, with a maximum theoretical force of 32 kgf at 1.0 MPa. Because this SKU includes the -S magnet, it works with the older CS1-M and DS1-M switches. If you upgrade to the MBL replacement, you must switch to the current CMSG, DMSG, or EMSG sensor family.
